The 32-year-old will next meet Frenchman Lucas Pouille in a rematch of their Australian Open semi-final in January, which was a straight-sets win for Djokovic. Pouille beat eighth seed Karen Khachanov of Russia 6-7(3), 6-4, 6-2 to make his third quarter-final – and first at the Masters 1000 level – of the season. Meanwhile, seven-time champion Roger Federer bowed out of the Cincinnati Masters after facing a shocking defeat to Russian qualifier Andrey Rublev in his Round of 16 match. The 21-year-old Rublev defeated Federer 6-3, 6-4 in just 62 minutes for his second top-5 victory in as many months.

“He was super clean. Defence, offence, serving well. Didn’t give me anything. He was everywhere. It was tough for me, but an excellent match by him. I was impressed… I think I just have to play better overall to hang with him,” said Federer while praising Rublev.

Rublev is through to his first ATP Masters 1000 quarter-final and will meet Coupe Rogers finalist and countryman Daniil Medvedev for a place in the semi-finals.
